Preparation of coal gasification fine slag-based
The coal gasification is the key process of clean usage of coal resource, which inevitably produces a large amount of coal gasification slag (CGS), and causes serious environmental pollution and ecological damage. The high ash content of coal gasification fine slag (CGFS) prevents the efficient utilization of residual carbon in CGFS. In this work, carbon …
